xumbo , @"PUDZILLA" many thanks for sharing your views on 'substances'. Based on these, we can say that the V delivers. And this is the end of positives. Smoking behaviour of provided substances is clear - and we cannot proof you wrong. The main reason is Rccrystals . You are not willing to disclose a molecular/chemistry formula and/or IUPAC for your stuff. This makes you haughty against your prospects, exposing yourself for such negative opinions. You should rethink your business model, as reputational risk linked to that, would definitely materialize.

Please note, that @"PUDZILLA" is not a random tester. He is credible and always objective. To defend yourself you need to provide molecular formulas of your stuff - to let us independently check how they behave.
